Description

Technical Field

[0001] The invention relates to the technical field of hydraulic support transport tooling equipment, in particular to a transport device for an advanced support. Background Art

[0002] The advance support is a mining equipment installed in the working face tunnel for the safe support of the intake and return air tunnels, replacing the support of the working face tunnel by single pillars. The advance support has the characteristics of high support strength, large support area, high safety and reliability, and simple overall operation. The advance support of the working face has begun to be promoted on a large scale. With the continuous development of society, the awareness of safe production has gradually strengthened, and the country has begun to vigorously improve the management measures for safe production construction in coal mines. Due to the poor stability and high work intensity of the single pillar support, manual movement of the single pillar is required during the advancement of the working face, which requires more manpower and material resources, as well as limitations such as low safety.

[0003] Common advance supports are arranged in a group of front and rear frames. The front and rear frames have the same structure and meet the requirement of 20m advance support for the working face as a whole. The front and rear frames are connected by push jacks. The structure is an integral top beam with a front beam, a four-link structure, and a split base. As the entire working face advances, when it is necessary to move to the next working face, the equipment on the working face needs to be moved. The middle support can be moved as a whole by a transport truck, while the advance support generally needs to be dismantled, and then the dismantled structural parts, pins, jacks, hydraulic systems, etc. are moved to the next working face separately. In this process, it is inevitable that various small parts will be lost, resulting in longer time for the support reassembly and a longer period of moving and reversing. In addition, the labor intensity of the workers is high, and the cost invested by the mine increases.

[0004] How to design a transport device for advance supports with clever design, simple structure, low cost, easy operation, which can realize overall transportation of advance supports in working face tunnels, reduce the cost of dismantling and transportation, reduce the time of moving and reversing the working face, save manpower and material resources, reduce waste of resources, and increase enterprise benefits is a problem that needs to be solved at present. Summary of the Invention

[0005] In order to solve the technical problems that when the existing common advanced support needs to be replaced to the next working face as the whole working face advances, the equipment on the working face needs to be relocated. The middle support can be transported as a whole by a transporter, while the advanced support generally needs to be disassembled. Then, the disassembled structural parts, pin shafts, jacks, hydraulic systems, etc. are respectively transported to the next working face. In this process, it is inevitable that various small parts are lost, resulting in an increase in the time for reassembling the support, an extension of the relocation cycle of the working face, a large labor intensity of workers, and an increase in the cost invested by the mine. The present invention provides a transporting device for the advanced support, which is designed ingeniously, has a simple structure, low cost, convenient operation, can realize the overall transportation of the advanced support in the roadway of the working face, reduce the disassembly and transportation cost, reduce the time for relocating the working face, save manpower and material resources, reduce resource waste, and increase the enterprise benefit.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a transporting device for an advanced support, including an advanced support base and a transporting device installed on the base. The advanced support base includes a pair of first bases and second bases arranged horizontally and in parallel. Fixed seats and sleeves for connecting the transporting device are provided on the side plates of the first base and the second base. The transporting device includes a connecting rod, a support plate, and multiple groups of reinforcing ribs. The support plate is a rectangular flat plate, and the reinforcing ribs are fixedly welded opposite to each other on the support plate to form a reserved groove for installing the connecting rod. The two side reinforcing ribs and the connecting rod form a cross-shaped structure. A fixing groove for inserting into the interior of the fixed seat is provided at the top end of the connecting rod, and a square retaining pin and a split pin are arranged in the fixing groove. The advanced support base and the transporting device are connected into an integral body by inserting the square retaining pin and the split pin into the fixing groove.

[0007] The number of the transporting devices is four to eight.

[0008] The depth of the reserved groove on the reinforcing rib is higher than the outer diameter of the connecting rod to limit the connecting rod in the reserved groove.

[0009] The number of the groups of reinforcing ribs is four.

[0026] The above is the basic implementation manner of the present invention, and further improvements, refinements, and limitations can be made on this basis: for example, the depth of the reserved groove 11 on the reinforcing rib 5 is higher than the outer diameter of the connecting rod 3 to limit the connecting rod 3 within the reserved groove 11.

[0027] The above is the basic implementation manner of the present invention, and further improvements, refinements, and limitations can be made on this basis: for example, the number of the reinforcing ribs 5 is four groups.

[0028] The above is the basic implementation manner of the present invention, and further improvements, refinements, and limitations can be made on this basis: for example, bolt mounting holes 8 and bolt assemblies for connecting a handling cart are further provided on the support plate 4.

[0029] Figure 3 It is a schematic top view structure diagram of the handling device of the present invention, which is mainly composed of three parts welded together. The serial number 3 is the connecting rod, which is the main stress-bearing member. The serial number 4 is the support plate, which is also the main stress-bearing member. The serial number 5 is the reinforcing rib, which mainly plays a strengthening role.

[0030] Figure 5 It is a schematic diagram of the connection form between the advanced support and the handling device. The serial number 2 is the fixed seat, which is mainly used to fix the connecting rod 3 with the serial number 3. Its fixing form is jointly fixed by the serial numbers 6 and 7 as shown in the figure. The serial number 6 is the square retaining pin, and the serial number 7 is the opening pin. As shown in the figure, the square retaining pin 6 passes through the fixed seat 2 and the fixing groove on the connecting rod 3 to fix the handling device. Finally, the opening pin 7 is inserted through the square retaining pin 6. This is the connection method of one handling device. The serial number 8 is the bolt fixing hole between the handling device and the handling cart. The following introduces the fixing method of the grouped handling devices, such as Figure 6As shown, the advance support base is a split base, with four handling devices mounted on each of the first and second bases 9 and 10. The handling devices are connected to the bases by a connecting rod 3 passing through a sleeve 1 on the base. The base's fixing seat 2 and the groove on the connecting rod 3 are secured to the base via a square stop pin 6 and a cotter pin 7. Once connected, the handling device's support plate 4 is parallel to the roadway floor.

[0031] In actual operation, the working process of the present invention is as follows:

[0032] The connecting rod 3 passes through the sleeve 1 on the first base 9 and the second base 10, the fixing seat 2 on the first base 9 and the second base 10 and the fixing groove on the connecting rod 3, and is fixed to the base through the square stop pin 6 and the cotter pin 7. After the connection is completed, the plane of the support plate 4 in the handling device is parallel to the bottom plate of the roadway. Figure 5 The connection form between the advance bracket and the transport device shown connects the transport device to the base in turn, with a total of 8 groups of transport devices. A transport vehicle is used on each side, and the bolt mounting holes 8 and bolt assemblies on the transport device are used to connect and fix the transport vehicle with bolts and nuts. Then start the transport vehicle to realize the overall transport of the advance bracket of the working face tunnel. This completes the transport of the advance bracket of the working face tunnel. After transporting the advance bracket to another working face tunnel, the transport vehicle finds a location for placing the bracket, and then removes the fixing bolts and nuts of the transport vehicle and the transport device. Secondly, remove the cotter pin 7 and square stop pin 6 that fix the transport device. Then the transport device can be removed. All the removed transport devices, bolts, nuts, cotter pins 7 and square stop pins 6 are sorted and stored. Finally, drive away the transport vehicle. This completes a complete transport process of transporting the advance bracket of the working face tunnel.

[0033] The present invention has a clever design, a simple structure, low cost and easy operation. It can realize the overall transportation of the advance support of the working face tunnel, reduce the cost of dismantling and transportation, shorten the time of moving and reversing the working face, save manpower and material resources, reduce waste of resources, increase enterprise benefits, and solve the existing common advance support. When the entire working face advances, it needs to be replaced to the next working face. The equipment on the working face needs to be moved. The middle support can be moved as a whole by a transport truck, while the advance support generally needs to be dismantled. Then the dismantled structural parts, pins, jacks and hydraulic systems are transported to the next working face respectively. In this process, it is inevitable that various small parts will be lost, resulting in a longer time for reassembling the support, resulting in an extension of the moving and reversing cycle, high labor intensity for workers, and increased cost investment by the mine. Technical problems such as this have good market prospects and development space for existing technologies.
